Dithering is a perceptual effect, so it's hard to tell without a Rift in front of you whether the pixel size would be too great to avoid it just looking like chroma noise. A non-static dithering pattern would probably be unnoticeable except in overall very dark scenes. In this regard, on-board dithering from an 24-bit input and software dithering and a native 18-bit input would give similar results.MSat wrote:As I respect your (as well as many other members of this forum) opinions, I would like to know what your thoughts are regarding the possible issues I mentioned with using dithering. Am I on the right track with thinking that it would not enhance the perceived colors but rather just introduce noise to the image given the low angular resolution?
However, there's also FRC (or 'temporal dithering'), which is harder to effectively replicate in software (the colour change frequency is ideally several times of the panel refresh rate). In this case, providing an 24-bit input would produce superior results to providing a 18-bit input.
